(Sports Network) - San Francisco 49ers head coach Jim Harbaugh said he wants
to go with the hot-hand at the quarterback position.

It is still unknown whether that will be Alex Smith or Colin Kaepernick, but
what the Niners do know is that they have to deal with the red-hot New Orleans
Saints this Sunday on enemy turf.

San Francisco has lived up to its billing as NFC contenders one season after
besting the New Orleans Saints in a divisional playoff game before coming up
short against the New York Giants in the conference title contest.

The 49ers lead the NFC West with a 7-2-1 record and are undefeated in their
past four games. That does include a 24-24 tie versus the St. Louis Rams on
Nov. 11, a contest in which Smith suffered a concussion.

Smith was hoping to start last Monday night's game against the Chicago Bears,
but was not cleared medically in time. That opened the door for Kaepernick to
make his first NFL start and he did not disappoint against a very tough
defense in a 32-7 win.

The 2011 second-round pick guided San Francisco to scores on each of its first
four drives and finished the game 16-of-23 passing with a pair of touchdown
throws, one each to tight end Vernon Davis and wide receiver Michael Crabtree.

His performance was the talk of the town and Harbaugh's comments after the
game preheated the oven for a quarterback controversy.

"We'll see. I usually tend to go with the guy who's got the hot hand. And
we've got two quarterbacks that have got a hot hand," said Harbaugh. "So,
thought Colin did an outstanding job. Thought he did a great job. Poise in the
pocket, pushing the ball and throwing with accuracy. Did a nice job running
the game plan."

Harbaugh, was on the sidelines Monday night despite being sent to the hospital
last Thursday due to an irregular heartbeat that needed treatment, wouldn't
commit to a starter on Wednesday.

"We'll let it play out," he said.

Though reports say that Smith had yet to be medically cleared, Harbaugh said
he expected his season-opening starter to be so this week and will make a
decision that is best for the team.

San Francisco will face a test on its path to a repeat division title as it
will play two straight and four of its next five on the road. That starts
against a Saints team that had won six in a row over the Niners before last
year's playoff setback.

The 49ers haven't beaten the Saints in the regular season since Jan. 6, 2002
in New Orleans.

No team in the NFC is perhaps as hot as the Saints, who have crawled back to
the .500 mark after an 0-4 start by winning three straight and five of six.
Their latest win came at the Oakland Raiders on Sunday as Drew Brees fueled
the 38-17 triumph with three touchdown passes.

Looking a bit lost in the wake of the bounty scandal that went down this past
offseason, assistant head coach Joe Vitt, filling in for the suspended Sean
Payton after serving his own ban, credited the team for battling through the
adversity.

"At 0-4, they stuck together and continued to work hard," said Vitt. "They
didn't point fingers. It's paying dividends now."

With the Atlanta Falcons pacing the NFC South with a 9-1 mark, a wild card
seems to be the Saints' best hopes of returning to the playoffs. And it isn't
shocking that their three-game win streak has encompassed November given the
team's 14-game winning streak in the month dating back to 2009.

"I think it's the process. They come in everyday as a player and try to get
better. We try to get better as a team. By November, you kind of define who
you are and get a little bit of confidence. That being said, I know what our
November record has been. The past doesn't dictate the future. It's going to
take another great week. With this team coming in, it will be a great
challenge," noted Vitt on Monday.

WHAT TO WATCH FOR

Who will be under center for the Niners is the biggest mystery leading into
the game.

Though he has failed to live up to the hype of being the top overall pick of
the 2005 draft, Smith has been a consistent presence at the quarterback spot
for the 49ers and nearly took them to the Super Bowl a season ago. Smith has
completed 70 percent of his passes in 2012 and has 13 touchdown passes to just
five interceptions while throwing for 1,731 yards.

Normally, an unwritten rule states that a player doesn't lose his starting job
due to injury, but Harbaugh said on Monday that he does not subscribe to such
a guide.

Should Smith not be medically cleared for this game, or if Harbaugh simply
decides to stick to Kaepernick, the untested 25-year-old will bring more
mobility and a threat to scramble to the gameplan, though he has been sacked
four times and fumbled the ball twice -- neither recovered by the other team
-- in his last two appearances.

Still, it is hard to argue with what Kaepernick did against a respected Bears
defense on Monday.

"It just felt good to be back out on the football field playing," he said. "I
mean, I thought we did a good job as an offense. We put points on the board as
an offense, our defense did a great job out there holding them. We came out on
top, so that was good."

Speaking of the defense, linebacker Aldon Smith was a giant thorn in the
Bears' side, recording a career-high 5 1/2 sacks in the win along with two
forced fumbles. Smith now leads the NFL with 15 sacks this season after
setting a new franchise rookie record with 14 sacks a season ago.

Aldon Smith's sack total versus the Bears was the second-highest single-game
total in club history, behind only defensive end Fred Dean's six sacks versus
New Orleans on Nov. 13, 1983. His 29 career sacks trail only Reggie White (31)
and Derrick Thomas (30) for the most by an NFL player through his first two
seasons in league history.

"I really just try to make people respect my power. I don't think I'm one of
the bigger linebackers or ends, but I want people to know there's some power
in here too," Aldon Smith said of his technique after beating Chicago.

Smith and his fellow star linebackers Patrick Willis and NaVorro Bowman face
worthy competition this weekend in the form of Brees, who extended his NFL
record of 53 straight games with a touchdown pass last weekend.

Making Brees tough is the fact that he spreads the ball out to many different
receivers, chief among them tight end Jimmy Graham, wide receivers Marques
Colston and Lance Moore, and running back Darren Sproles, who is on track to
return for this game after missing three in a row with a left hand injury. He
was close to returning versus the Raiders following surgery, but swelling in
the hand led him to be held out.

Sproles is a big weapon for Brees as he averages 4.5 yard on 26 carries this
season while adding 39 receptions for 323 yards with four touchdowns.

Safety Malcolm Jenkins helped key New Orleans' win last weekend, coming up
with six tackles, a pass defensed and an interception he returned 55 yards for
a score in the opening quarter.

His first pick since 2010 was just the latest example of an improving Saints
club.

"I continue to say the same thing. We go out now, we practice the right way,
we prepare the right way, we watch film. We do all the little things that we
need to do to find ways to win games. I think we are doing a good job of that
now," said linebacker Jonathan Vilma.

OVERALL ANALYSIS

A possible playoff preview is set to go down in New Orleans and the battle
figures to be a close one.

Kaepernick could throw a wrench in the Saints' preparation plans due to his
difference in style from Smith, who was excellent versus New Orleans in the
playoffs last year. He threw for 299 yards, ran for a score and threw three
touchdown passes, including the 14-yard game-winner to Davis with nine seconds
to play.

That score capped a 34-point frame by the clubs and came just 1:26 after Brees
hooked up with Graham on a 66-yard score.

The Saints will need to be careful not getting over-excited for this game
given last season's results.

"They eliminated us in the playoffs last year. At the end of that game, our
hats were off to them. They won 15 games. Take a look at them statistically as
to where they were a year ago when they beat us," said Vitt.

"We ran into a buzzsaw last year and they beat us. This is a new season. This
is a new set of challenges. This is a new week and this is our next opponent."

Vitt should have his club focused and the looming quarterback controversy
plaguing the Niners' locker room won't be a welcomed addition at all.
